New Enerpac cube jack

International high-pressure hydraulics specialist Enerpac has launched the SCJ50 50T cube jack. Enerpac said it is designed to provide an alternative to traditional climbing jack systems, offering contractors a safer alternative to jacking and packing with wooden cribbing.

Enerpac said the SCJ50 works in a similar way to its other current jack-up systems but is simplified as electrical controls are not required. Blocks are stacked manually, with a mechanical lock on the up stroke and down stroke. The operation is incremental; at the end of the up stroke the lock engages. Once engaged, the lift cylinder is retracted and another block can be added.

The SCJ50 lifts up to two metres and has small footprint compared to traditional climbing jack systems, Enerpac added, making it suitable for use in space-restricted sites.
